Modern interior design came about as a reaction to the ornate and almost baroque styles that came before it. As such, the main focus of this school of design is to act as the antithesis of of those other looks. Rather than having lots of details and embellishments, modern furniture relies on clean lines and stark contrasts.
Traditionally, choosing furniture for a modern space meant staying within the Art Deco, Shaker or Mission styles. More recently, Scandinavian-inspired products have also been included in this category. Whichever design your bathroom furnishings are, try to ensure that they are as simplistic as possible and have a clearly defined shape.
